买卖信号

**买入信号：** 1. 金叉：DIFF上穿DEA，且DEA<0，21周期内第一次金叉 2. 二金叉~九金叉：DIFF上穿DEA，DEA<0，分别表示第2-9次金叉 3. 底背离：MACD底背离信号（价格创新低但MACD未创新低） 4. 三全底：金叉、二金叉、底背离同时满足 **卖出信号：** 1. 顶背离：MACD顶背离信号（价格创新高但MACD未创新高） **特殊信号：** - 六金叉：标注为"黄金底" - 七金叉：标注为"白金底" - 八金叉：标注为"钻石底" - 九金叉：标注为"金钻底"

用法

1. **适用场景**：中长线趋势交易，主要用于判断MACD金叉的强度和背离情况 2. **金叉意义**：连续多次金叉说明趋势转强概率增加，九次金叉（金钻底）为最强买入信号 3. **背离信号**：底背离是重要的买入机会，顶背离是卖出信号 4. **注意事项**： - 金叉信号要求DEA<0，即在空头市场中金叉更具参考价值 - 多次金叉需要配合其他技术分析综合判断 - STICKLINE颜色变化可辅助判断MACD柱状线的涨跌 5. **三全底**：同时满足金叉、二金叉、底背离三个条件，是较强的买入信号
